To all wie/om t may it lmown that l, FRANK' G. Drinnen, a citizen 'of the United States, and resident of Broolrl in the county of gs and t State of ew York, have invented certain new and useful Improvements in Shoes, oft

which the following is a specification. s The invention relates to the inner-sole portion of shoes and boots, and it consists in the w novel features and structure hereinafter de scribed, and particularlypointed out in the claims. i

@ne of the principal objects of the invention is to produce an inner sole oir particular te arch formation and capable, when in use, of

maintaining its form and integrity even under the weight of a heavy person who may be wearing the'shoes. Another purpose of the invention is to provide an innersole 2@ structure containing a metallic arch prop or support and of particular formation and with the prop so disposed and held that it will leave a smooth surface at the top of the inner sole and not interfere with the propel @d sewing and manufacture of the shoe in accordance with lmown mechanism and methods.

The invention will be fully understood from the detailed description hereinafter 3o presented, reference being had to the accompanying' drawings, in which:

Fig. 1 is a bottom view of an inner-sole constructed in accordance with and embodyin the invention;

te iig. 2 is an edge view of the `same,taken :from the left hand side of Fig. l;

Fig. 3 is a bottom view of the same, with the metallic arch prop or *supportand the lower covering layer or ply roved from 4@ the main body of the sole ;v

Fig. d isa vertical section through the sole of my invention, taken on the dotted line 4 4 of Fig. l;

Fig. 5 is a transver section through the t@ saine, taken on the dotted line 5`5 of Fig.

4 and 5Fig. '6' is a detached top view of the metallic .arch pre or support which l embed within the so e.y 5o

body of the inner-sole or inner-sole pro er, 1l the metallic arch prop or support, an '12 a lower layer or ply oi? leather which l seln the drawings, l@ designates the main `cure to the lower surface of the sole l0 and over the lower surface of the su port 11 ee which becomes embedded within ta sole o the shoe.

The inner-sole 10 will be of suitable edge outline and formed with such customary features, incident to the manufacture of a shoe, eo

as may be required. A feature of the sole l() having -to do with my invention resides in the upwardly arched and curved side member 13 which is integralwith the arch portion' f the sole 'and curves upwardly ee therefrom to lit against the curvature at the innerside of afoot forwardly of the heel. 'lhe upwardly arched member 13- has a convexly curved upper edge and is of sub= stantial @n so esto engage a large lo surface of the foot -and adord' a substantial support at the side of the arch portiono a foot. The sole 10 has formed in its lower surface, at the arch-portion thereof, a recess or socket 14 of a form and size to snugly 75 receive the metallic arch 'pro or support 1l, this recess starting inwar y from near the outer side edge of the sole ll0 and ex tending upwardly alon the curvedmember 13 of said sole to near-t supper edge there- 8o of. The arch prop or support 11 is curved correspondingly with the member i3 of the' sole and with those portions-of the sole which merge into said member 13, as shown in vFig. 5, andl said arch prop or support 1-1 e5 is formed with p-unctures l5 whose ianges entend upwardly and are driven into the material .of the sole lO from the lower side thereof, as shown in Fig. 5, whereby said arch prop or sup-port becomes anchored or secured a0 to the sole l0 within the outline ot the recess or seat 1li provided therefor. The metallic arch prop or support l1 by extending from near the outer e ge of the sole l0 in a direction toward the inner .edge thereof and upa5 wardly` along the member 13 to approximately near the upper edge thereof, is cnabled to maintain the integrity of the arch of the sole and of the initial. Aformation of the member 13 and to eiectnally-resist the 10o weight of a heavy person who mayvvear the shoe. lt will be. seen on reference to Fig. 6 that vthe arch support or plate 1i is of special configuration and that the curved upwardl extending side thereof has at its base a widt ma equal to the full length of said support and l that the upwardly extending curved portion of said plate or support 11 is of considerable area and extends upwardly to provide a support for the bottom and side of the arch portion of the human foot, said plate extending upwardly to a point enabling it tosupport the plantar arch of the foot particularly along the line of the tarsal bones, it being apparent that the proportions and location of the supporting plate 11 are such as to take care of the plantar-.ligament of the foot and those bone portions at the joints between the heel bone 4and the scaphoid ubones of the human foot, thereby distinguishing my invention from an ordinary longitudinal arch support having a little side wing appended t0 it.

The arch prop or support 11 is' covered over at its lower surface by the layer .of leather 12 which, as shown, extends from the usual sewing lip or ridge 16 adjacent to the outer side edge of the sole 1() toward the inner side edge of said sole and up along the arch member 13 of thesole, said covering layer orply 12 being secured near its outer side edge by sewing 17 to the sole 10. The coveringlayer 12 constitutes an extra ply for'the arch member 13 y its upper edge is secured thereto by aline Aas of sewing 19, and said layer 12 adds material stability to the inner sole of the shoe and when in its final position forms a portion thereof. The layer 12 helps to concea and support the arch prop 11 and aiords a q proper surface against which the shoe-.upper and outer sole may be applied in accordance with customary methods of manufacture. The arch prop 11 does not extend to the extreme outer side edge ot the ysole 10,

but is set inwardly therefrom, as indicated in Figs. 1- and 3, so as not to interfere with the proper 'application of the upper -and outer sole during the manufacture oit the shoe.

The layer 12 is slit or undercut, as at the line 20, to form a projecting lip 21 to which the upper of the shoe may be sewed, thus permitting the proper association of the other parts of the shoe with the inner-sole without the stitches passing through the arch prop or plate 11, the lip 21 coinciding with or constituting an extension of the usual ridge or lip 16l where it extends alongthe inner side edge of the sole, as shown in Fig. 1. l provide the li 21 so as to make it possible to carry on the propermanufacture of the shoe and at the same time have the metallic arch prop or support 11 extend alon the undersurface o 'the sole 10 and up a ong the side member 13. vIt will be seen on reference' to Fig. 5 that the lip 21 may be utilized as an edge for the sewing operation Without interference with or from l the plate 11. The usual slit or undercut ved to the sole of the solev and atv side edge of the sole 1() and this undercut receives, by preference, the adjacent edge of the layer 12, as indicated in Fig. 5.

The upper surface of the sole 1Q is under- 23 (Fig. to receive the by which the outer or left the covering layer 12 is secur- 10, the undercut 23 permitting me to secure thelayer 12 in position without creating a ridge, dueto the sewin on the upper `surface of the sole 10. l a so form an undercut 24 in the upper .surface of the cut along the line line of sewing 17 hand edge of upper portion of the side arch-member 13 to admit of the sewing 19 for securing the upper edge of the layer 12 in position without creating a ridge on the inner surface of said member 13.

My invention thus comprises the construction hereinbefore described involving the inner sole 10, inner' side arch-member 13, metallic arch prop or support 11 and lower layer 12 concealing the arch prop 11 and serving as an extra ply along the arch of the sole and said member 13, provision being made for preventing the formation of ridges 'at the upper surface of the sole and said member 13 and for the proper sewing of the upper or other portions of the shoe to the inner-sole without interference from or by reason of the presence of the metallic arch prop or support 11.

My invention has been designed with the View of producing a shoe which will adeuately and -properly support the arch. of the foot and resist the severe strains which come upon the arch portion of a shoe when the shoe is worn by a heavy person.

What l claim as my invention and desire to secure by LetterssPatent, is
